Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Amino-5-methylphenyl)phosphonic acid.
CATO supplies (2-Amino-5-methylphenyl)phosphonic acid (CAS 69675-98-5), a certified reference material (molecular formula C7H10NO3P, MW 187.13 g/mol) for analytical method development and quality control.
Owing to an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, (2-Amino-5-methylphenyl)phosphonic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (2-Amino-5-methylphenyl)phosphonic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
