- Limpieza
Application
- Desbloqueo de la adsorción de alto rendimiento de HCl a temperaturas elevadas: en esta investigación se demuestra el uso de una disolución de ácido clorhídrico para sintetizar óxidos mixtos de Ca-Mg-Al robustos. Estos materiales son cruciales en aplicaciones medioambientales para la adsorción de gases ácidos, demostrando el papel del ácido clorhídrico en el desarrollo de soluciones para combatir la contaminación atmosférica (Cao et al., 2024).
- Inhibición sostenible y verde de la corrosión del acero dulce: el ácido clorhídrico se utiliza aquí para probar nuevos inhibidores ecológicos de la corrosión. Esto es vital en industrias donde es crucial mantener la integridad del material frente a ataques químicos, destacando el papel del ácido clorhídrico en aplicaciones innovadoras de la ciencia de los materiales (Rizi et al., 2023).
- Síntesis de nanovarillas de óxido de zinc a partir del precursor borato de zinc: en este estudio se utiliza ácido clorhídrico en la síntesis de nanovarillas de óxido de zinc, importante para aplicaciones de supercondensadores. Subraya el papel crucial del ácido clorhídrico en la investigación sobre nanomateriales, ampliando los límites de la tecnología de almacenamiento de energía (Lefdhil et al., 2023).
- Un procedimiento mejorado de digestión y análisis del silicio en el tejido vegetal: el ácido clorhídrico se emplea para digerir tejidos vegetales y analizar el contenido de silicio, mejorando las metodologías de investigación agrícola y biológica. Esta aplicación refleja la importancia del ácido clorhídrico en estudios científicos que requieren un procesamiento químico preciso (Langenfeld y Bugbee, 2023).
- Ciclación intramolecular formando enlaces N-N(+) de O-tosiloxi β-aminopropioamidoximas y reacción de intercambio iónico: en esta investigación, el ácido clorhídrico desempeña un papel clave en la síntesis orgánica, demostrando su versatilidad en el desarrollo de compuestos farmacéuticos. El estudio proporciona información sobre la síntesis de compuestos orgánicos complejos, que son vitales en la química medicinal (Kayukova et al., 2023).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How can the outer metal shipping container be safely removed to access the 2.5L container of Hydrochloric acid inside?
1 answer-
The packaging used for the Hydrochloric acid is described as an "8" CS OVERPACK CAN (802), SEAMED." There are two types of overpack cans: one resembling a paint can and the other resembling a large can of corn. For the paint can-style, a flat-bladed screwdriver can be used to pry off the lid, while the can of corn-style may require a can opener. Inside the can, there should be packaging material such as a side panel and absorbent sheet. The bottle itself is a PVC-coated glass bottle designed to prevent shattering if it is accidentally dropped.
