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 3-Chloro-2-hydroxy-5-(hydroxymethyl)benzaldehyde.
3-Chloro-2-hydroxy-5-(hydroxymethyl)benzaldehyde (CAS 832097-02-6), molecular formula C8H7ClO3 and molecular weight 186.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-2-hydroxy-5-(hydroxymethyl)benzaldehyde (C8H7ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Chloro-2-hydroxy-5-(hydroxymethyl)benzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
