Industrial grade 98% 98.5% 99,99.5% 1,3-Dichlorobenzene 541-73-1

Product Overview

Product Overview 1,3-Dichlorobenzene (m-dichlorobenzene) is a clear, colorless to pale yellow aromatic liquid, carrying two chlorine atoms in the meta (1,3) position. It is the least common of the three dichlorobenzene isomers, but chemically the most valuable as an intermediate: its meta directing chlorines make it the starting point for a family of triazole, fungicides and azo dye precursors. Industrially, m-DCB is recovered from mixed dichlorobenzene streams by extraction crystallization and purified to ≥ 99.5%. It is the key raw material for triazole fungicides including propiconazole, difenoconazole and imazalil, and for dyes and pigments of the naphthol class. One isomer, the agrochemical backbone of the dichlorobenzene family.

Core value propositions:

● a building block of triazole fungicides and herbicides (propiconazole, difenoconazole, imazalil and more);

Dye & Pigment Intermediates:

● a starting material for naphthol AS dyes, AS-ITR and fast-carmine pigments;

Solvents & Specialty:

● a solvent for organic synthesis and a specialty intermediate for fine chemicals.

Product Information (Quick Facts)

Chemistry & Isomers

Dichlorobenzene exists as three isomers — ortho (1,2-), meta (1,3-) and para (1,4-) — which are separated from mixed chlorination streams by distillation and extraction crystallization. In m-DCB, the two chlorine atoms occupy the 1 and 3 positions, which leaves the 5-position highly activated for electrophilic substitution. That positioning is what makes m-DCB the favored precursor for triazole fungicides and pharmaceuticals, where the meta-chlorophenyl ring is a recurring pharmacophore.

Commercially, m-DCB is the minor isomer of mixed dichlorobenzene production, so supply is tied to the economics of its para- and ortho-isomers. Industrial/intermediate grade (≥ 99.5%) serves agrochemical, dye and solvent use

Key Features & Benefits

FAQ

Q1: What is 1,3-dichlorobenzene used for?

1,3Dichlorobenzene is used mainly as a chemical intermediate: in agrochemicals for triazole fungicides (propiconazole, difenoconazole, imazalil, hexaconazole); in dyes and pigments for naphthol AStype intermediates; and as a synthesis solvent.

Q2: What is the difference between 1,3-, 1,2- and 1,4-dichlorobenzene?

The three isomers differ in chlorine position and market: 1,4- (para) is the most abundant, used for moth repellents, deodorants and PPS resin; 1,2- (ortho) is a solvent and intermediate; 1,3- (meta) is the least abundant but the key agrochemical intermediate, because its metachlorophenyl pattern appears in triazole fungicides. They are separated from the same mixed chlorination stream.

Q3: Which grade should I buy?

Industrial/intermediate grade (≥ 99.5%) serves agrochemical, dye, solvent and general synthesis use. Specify your application and quality requirements when ordering.

Q4: Is 1,3-dichlorobenzene safe to handle?

1,3-Dichlorobenzene is irritating to eyes, skin and airways, combustible, and is under EPA IRIS toxicological assessment (liver/kidney effects at high exposure; CDC/ATSDR provides medical management guidance). Use gloves, goggles and adequate ventilation, avoid inhalation and skin contact, and keep it away from ignition sources. It is an industrial chemical, not a food or drug ingredient.
