Questions about Reagents for analysis (Ph. Eur., ASTM, DIN)

Why Reagents for analysis (Ph. Eur., ASTM, DIN)?

A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.

A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
