General description

Bromomethane-d3 (CD3Br) is a perdeuterated isotopomer of methyl bromide. Its vibrationless Rydberg transitions have been investigated based on photoabsorption spectral data. The infrared spectrum of CD3Br has been analyzed in the range 2000-7000cm-1.

Packaging

All gas volumes are quoted at Standard Temperature and Pressure (STP) and not at Normal Temperature and Pressure (NTP). One STP Liter is 7.7% more gas than one NTP Liter.
Shipping of this product by air freight is forbidden.
Outside of the U.S., ocean freight shipment is required and will result in substantial additional expense.
Standard 10 g quantity is packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressure at 21ºC is 13 psig for 10 g. This pressure is slightly above atmospheric pressure. Care must be taken when extracting product from the cylinder.
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.

Recommended products

Stainless steel control valves Z146951 or Z187224 is recommended.
