Chemical Structure

1,3-Dibromo-2-methylpropene (E/Z Mixture) CAS 35911-17-2 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 1,3-Dibromo-2-methylpropene (E/Z Mixture).

1,3-Dibromo-2-methylpropene (E/Z Mixture) (CAS 35911-17-2) is a high-purity analytical reference standard with the molecular formula C4H6Br2 and a molecular weight of 213.90 g/mol.

1,3-Dibromo-2-methylpropene (E/Z Mixture) (C4H6Br2) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1,3-Dibromo-2-methylpropene (E/Z Mixture) 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.
