ДИЛЬДРИН ХЛОРГИДРИН

Description

Dieldrin chlorohydrin is registered under its own CAS 62059-42-1 separately from dieldrin (CAS 60-57-1). The card formula C12H8Cl6O, C3H7ClO2 indicates a composition of two fragments - the chlorinated cyclodiene insecticide dieldrin (C12H8Cl6O) and chlorohydrin (C3H7ClO2, propylene chlorohydrin) - that is, we are talking about an adduct/solvate of dieldrin with chlorohydrin, registered as a separate substance for analytical purposes. Dieldrin itself belongs to the organochlorine insecticides of the cyclodiene series, obtained by epoxidation of aldrin.

The very name “chlorohydrin” in this context does not indicate the functional group of dieldrin, but the second component of the compound formula - this should be taken into account when searching for a substance in databases, where it may appear under different spellings and synonym groups.

Basic Attributes

• CAS No: 62059-42-1
• Chemical formula: C12H8Cl6O, C3H7ClO2
• Molecular weight: 491.452

Class and origin

Dieldrin is a persistent organochlorine pesticide that was widely used in the mid-20th century as a broad-spectrum contact and intestinal insecticide, but was subsequently banned in most countries due to its persistence in the environment and bioaccumulation. The chlorohydrin form is a derivative compound used primarily as an analytical standard or comparative sample in the study of residual quantities and transformation products of dieldrin in environmental objects.

Scope of application

Due to the lack of detailed data in the dump for this specific CAS number, the scope of application is limited for reference: analytical chemistry (reference/standard for chromatographic analysis of organochlorine pesticide residues), studies of dieldrin metabolism and degradation. Independent agricultural or domestic uses for a substance under this CAS are not documented in the available sources.

The practical interest in such derivatives is related to environmental monitoring: dieldrin and its derivatives persist for years in soil and sediments, and laboratories monitoring residual contaminants use related compounds as reference points in the calibration of chromatographic and mass spectrometric methods.

The compound formula of the card is a direct indication of the nature of the substance as a product of joint registration of two components, similar to how in the same batch the hydrochloride and acetate salts of diethanolamine are registered with separate CAS numbers: the combination of the active compound with an additional fragment forms an independent entry in the database.

When working with the purchase of such a highly specialized reagent, it is worth requesting from the supplier a quality certificate and a certificate of analysis for a specific batch, since publicly available databases do not contain a sufficient volume of verified physical and chemical characteristics for this CAS number.

Toxicity and danger

As a dieldrin derivative, the substance should be considered in the context of the general toxicology of cyclodiene insecticides: dieldrin is toxic to humans and aquatic organisms, persistent in soil and capable of bioaccumulation in fatty tissues. There are no specific LD50 values, transport codes and GHS classification for the CAS 62059-42-1 card in the dump - citing them by analogy with dieldrin is prohibited by the “don’t invent anything” rule.

Historically, cyclodiene insecticides in this group, including dieldrin, aldrin and chlordane, were withdrawn from agricultural use in most countries around the world by the end of the 20th century and included in the list of persistent organic pollutants of the Stockholm Convention, which determines strict management of any related compounds.

Storage and transportation conditions

Store as an organochlorine compound with caution: in a sealed container, in a cool, dry room, isolated from sources of open flame and strong oxidizing agents, out of reach of unauthorized persons, taking into account the general environmental hazard of the group of cyclodiene organochlorine compounds.

When working with samples of this kind in laboratory practice, general regulations for handling persistent organochlorine compounds are followed: minimizing the volume of open contact, using exhaust equipment and separate collection of waste for subsequent specialized disposal.
