Measured properties
Values somebody obtained from a sample and published. Where two sources report the same property they are both shown, in the units each used — a disagreement between them is information, and averaging it away would be inventing a number neither one gave.
- Boiling Point
- 306 °F at 760 mmHg (decomposes) (USCG, 1999)
- 152 °C AT 760 MM HG
- Melting Point
- 0 °C
- Density
- 1.22 at 68 °F (USCG, 1999) - Denser than water; will sink
- 1.2166 20 °C/4 °C
- Solubility
- SOL IN ETHER, ACETONE, BENZENE

- Vapor Pressure
- 7 mm Hg @ 85-87 °C
- Vapor pressure, kPa at 85-87 °C: 0.009
- Flash Point
- 227 °F Vigorous decomposition occurs at these temperatures; thus these values are anomalous due to the effect of the decomp. products (benzyl chloride and CO2). (USCG, 1999)

- Refractive Index
- INDEX OF REFRACTION: 1.5175 @ 20 °C/D
Calculated properties
Derived from the structure rather than from a sample. These are reproducible and they are not measurements: a calculated partition coefficient and a measured one can differ by a long way, and where both exist they are listed apart on purpose.

The molecule in three dimensions
The drawing above is a diagram of what is bonded to what. A molecule is not flat, and the model here is one low-energy shape generated from the connectivity — useful for seeing which groups can reach each other, and not a measured structure. A real sample is a population of conformations, interconverting.
Reactions it appears in
Other names for it
The systematic name on this record is benzyl carbonochloridate.
The sources also call it Benzyl carbonochloridate, Carbobenzoxy chloride, Benzyl chlorocarbonate, Benzylcarbonyl chloride, Benzyloxycarbonyl chloride, Carbobenzyloxy chloride, Carbonochloridic acid, phenylmethyl ester, Chloroformic Acid Benzyl Ester, Chloroformic acid, benzyl ester, Benzylcarbonochloridate, Formic acid, chloro-, benzyl ester.

Seen alongside it in reaction records
Molecules that appear in the same recorded reactions as Benzyl chloroformate. This says nothing about structure: most of them are the bases, solvents, ligands and catalysts the chemistry needed, and they are here because somebody put them in the same flask.

What this page does not claim
The identifiers are what the source record holds, copied rather than recomputed. Measured values are reported as their source gave them, units and all; calculated values are marked as calculated and are not measurements. Where a field is absent the page says so, because a blank cell reads as a zero and a guessed value reads as a fact.
Nothing here is a hazard assessment, a purity statement or advice about handling a sample. A flash point quoted from a safety database is a number somebody published, not a judgement by us about whether this molecule is safe for what you intend.
