Amylmetacresol EP Impurity I CAS 173851-73-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Amylmetacresol EP Impurity I.

Amylmetacresol EP Impurity I (CAS 173851-73-5) is a certified pharmaceutical impurity reference standard with the molecular formula C12H16O2 and a molecular weight of 192.25 g/mol.

Based on its molecular formula C12H16O2, Amylmetacresol EP Impurity I contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 192.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Amylmetacresol EP Impurity I 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.
