Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Pyridin-2(1H)-ylidene)acetaldehyde.
CATO supplies 2-(Pyridin-2(1H)-ylidene)acetaldehyde (CAS 119884-58-1), a certified reference material (molecular formula C7H7NO, MW 121.14 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(Pyridin-2(1H)-ylidene)acetaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 121.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(Pyridin-2(1H)-ylidene)acetaldehyde 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.
