https://www.sigmaaldrich.com/specification-sheets/105/121/D7148-BULK.pdf
For compounds with primary amino (-NH2) groups like this one, the most common route of decomposition is oxidation to the amine-N-oxide. And oxidation of a relatively small percentage of the 3,4-Diaminopyridine could cause the material to darken significantly.

試薬の色についてご質問です。 試験成績表のSpecificationの項目は、Colorless to Very Dark Brownとなっていますが、この色の差が生じる要因を教えていただくことは可能でしょうか。 購入したlotはVery Dark Browでした。他社製品の色はかなり薄い印象です。
