Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including XX3QN28JUX 4894-61-5 1-Chloro-2-butene, (2E)- 2-Butene, 1-chloro-, (2E)- (E)-1-Chlorobut-2-ene (E)-1-Chloro-2-butene trans-1-Chloro-2-butene EINECS 225-516-5 UNII-XX3QN28JUX.

CATO supplies XX3QN28JUX 4894-61-5 1-Chloro-2-butene, (2E)- 2-Butene, 1-chloro-, (2E)- (E)-1-Chlorobut-2-ene (E)-1-Chloro-2-butene trans-1-Chloro-2-butene EINECS 225-516-5 UNII-XX3QN28JUX (CAS 4894-61-5), a certified reference material (molecular formula C4H7Cl, MW 90.55 g/mol) for analytical method development and quality control.

The molecular framework of XX3QN28JUX 4894-61-5 1-Chloro-2-butene, (2E)- 2-Butene, 1-chloro-, (2E)- (E)-1-Chlorobut-2-ene (E)-1-Chloro-2-butene trans-1-Chloro-2-butene EINECS 225-516-5 UNII-XX3QN28JUX (C4H7Cl) is characterized by chlorine substitution. 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), XX3QN28JUX 4894-61-5 1-Chloro-2-butene, (2E)- 2-Butene, 1-chloro-, (2E)- (E)-1-Chlorobut-2-ene (E)-1-Chloro-2-butene trans-1-Chloro-2-butene EINECS 225-516-5 UNII-XX3QN28JUX 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.
